Cambo Wide DS problem

But for some reason I am unable to focus and all seems unsharp when focussing, am I missing something here? It cannot be used in combination with the 65mm lens? I use a grid glass to focus without any issues on my older Cambo (580 and 750) series.

I ask because i have a cambo 470 heilical designed for a 47mm XL, but I have a 47mm digitar lens. The XL has a considerably longer back focus than the digitar. The helical wont get infiniti with the digitar even when adjusted.
Oh wait never mind that means I need the lens closer to the focal plane not farther. Sorry answered my own question.
